Main Unit Preparation
Before operation, ensure the battery is loaded. Follow these steps for initial setup:
-
Setting Speed Scale:
Press the AC button to clear all data. Select either "mile/h" or "km/h" by pressing the Start/Stop button, then press the Set button to confirm.
-
Setting Wheel Circumference:
Measure your wheel circumference by marking the tire and measuring one full revolution, or use the cross-reference table. To set, press the Set button when the default circumference (e.g., 2155mm) is displayed. Use the Start/Stop button to increase and the Mode button to decrease the value. Press Set to confirm. The circumference can be between 10mm and 2999mm.
To reset or change the circumference later, set the unit to "(O)" mode, stop it, and press the Set button.
-
Setting the 24-hour Clock:
Enter the clock mode by holding the Mode button for over 2 seconds. Stop the unit and press the Set button. The minute figures will flicker; use the Start/Stop button to adjust. Press the Mode button to adjust the hour figures. Press Set to finalize. For accuracy, use a radio time signal.
-
Replacing the Battery:
When the display becomes faint, replace the CR2032 battery. Ensure the new battery is fitted correctly. Replacement should be done promptly (within 20 seconds). Avoid pressing buttons during replacement. If unusual display or non-responsive buttons occur after replacement, press the AC button to reset (this will erase all data).
Button Functions
The cyclocomputer has three main buttons:
- Mode Button (Left): Cycles through display modes. Holding for over 2 seconds displays the 24-hour clock.
- Start/Stop Button (Right): Starts/stops measurement of Trip Distance and Elapsed Time. The speed scale symbol flickers during operation. In Auto Mode, can switch the main display between Current Speed and Cadence.
- Set Button (Middle): Used to change settings (Wheel Circumference, Clock, Auto Start/Stop) when the unit is stopped in the respective modes.
Additional buttons:
- AC Button: Clears all data and resets the unit. Use only when irregular display or no display occurs.
Measuring and Display Functions
The cyclocomputer measures and displays the following:
- Current Speed (S): Displays speed updated once per second. In Auto Mode, can be shown on the sub-display.
- Total Distance (Odometer): Continuously measured distance. Resets to zero after 99,999 miles/km.
- Maximum Speed (M): Records the highest speed achieved. Resets to zero with a reset operation.
- Average Speed (A): Calculates average speed from start. Displays "(.E)" if limits are exceeded.
- Trip Distance (D): Distance covered since the last reset.
- Elapsed Time (T): Time duration since the last reset. Resets to zero after 10 hours.
- Cadence (C): Pedal revolutions per minute (rpm), displayed on the sub-display or main display in Auto Mode.
- 24-hour Clock: Displays the current time.
Auto (Automatic Start/Stop) Function
This function automatically starts and stops measurements based on wheel movement. The "AT" symbol appears when active. In Auto Mode, Elapsed Time is only counted when the wheel is revolving. Pressing the Start/Stop button in Auto Mode can switch the main display between Current Speed and Cadence.
Power Saving Function
If the unit receives no input for 60-70 minutes, it enters a power-saving mode, displaying only the clock. Pressing any button or receiving a sensor signal will exit this mode.
Troubleshooting
Address common issues:
- Slow Display Response: May occur at low temperatures (below 0°C/32°F); normalizes as temperature rises.
- No Display: Check if the lithium battery needs replacement.
- Incorrect Data: Perform an "All Clear" operation.
- Current Speed / Cadence Not Appearing:
- Clean contacts on the main unit and bracket.
- Ensure correct distance and alignment between sensor and magnet. Refer to mounting instructions.
- Check for wire breakage; replace the bracket/sensor part if necessary.
- Transmission Signal Loss (Damp/Wet Conditions): Water/condensation on contacts can interrupt transmission. Wipe contacts dry. A water-repellent silicon gel can be applied to contacts (avoid industrial types).
- Start/Stop Button Not Working: Ensure the unit is not in Auto Function, as the Start/Stop button is inactive in that mode.
Mounting Instructions
Follow these steps to mount the cyclocomputer and sensors:
Wire Securing/Bracket Mounting
Clamp the wire using the securing tape and clip, routing it along the outer cable to the handlebar. Ensure slack for handlebar operation. Use rubber pads (1mm or 2mm) if needed for handlebar diameter.

Main Unit Mounting
Slide the main unit onto the bracket from front to rear until it clicks. To remove, push the lever and slide forward. Test by spinning the wheel to check for speed display and revolving pedals for cadence display. Adjust sensor/magnet positions if needed.

Wheel Sensor/Magnet Mounting
Attach the wheel magnet to a spoke, ensuring it passes through the magnet correctly. Mount the wheel sensor to the rear of the left chainstay using Sensor Bands A and B. Align the magnet's center with the sensor's marking line, maintaining approximately 1mm clearance. For ATB/MTB bikes with wider gaps, ensure close proximity without touching.

Cadence Sensor/Magnet Mounting
Secure the cadence magnet to the inside of the left crank using adhesive tape and wire clip. Attach the cadence sensor to the front of the left chainstay using Sensor Bands A and B. Align the magnet's center with the sensor's marking line, maintaining approximately 1mm clearance.
